- GTX 1080 STRIX
-Noctua - NH-U12S 55.0 CFM CPU Cooler
-Asus - STRIX Z270-E GAMING ATX LGA1151 Motherboard
-Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000 Memory

-EVGA - SuperNOVA G3 750W 80+ Gold Certified Fully-Modular ATX Power Supply


Problem:

I have tried many ways to turn the monitor on but it does not work. Is it because of the motherboard or is it because of something else because everything that I brought are brand new. When plugging in the HDMI or a VGA to DVI port to the graphic card, the monitor doesn't turn on and it said "no signal". Also, everything boost up and light comes up. I have tried many ways and read many threads that are related to this problem, but it seems that it does not help me in solving this issue. I m so desperate for this new computer, Please help me, PLEASEEE!!!!!

Firstly, I assume you have a converter of some sort? You can't plug a HDMI cable into a DVI port.

Try factory resetting your monitor. If that doesn't work, connect a cable to your onboard display (meaning the problem could be the GPU). If that doesn't work, connect to a different monitor (if that works the problem could be your main monitor).
